Dolby is a unifying audio technology that brings vibrant, high-quality surround sound to all your electronic entertainment. Whether you're watching movies, TV shows, online videos, or concerts, Dolby assures that you'll always get consistent audio quality.
Dolby incorporates the latest and most advanced algorithms. It uses both psychoacoustic and cognitive models of audio perception, based on more than four decades of research into how people experience sound.
At its core, Dolby technology represents a very efficient way for movie studios, television networks, and other content providers to compress the size of multichannel audio files without impairing the sound quality. The smaller the file, the easier it is to distribute. With Dolby, it's possible to include a full 5.1-channel audio mix on a film print or a DVD, or as part of a TV broadcast. This expands the creative palette for artists, and allows those of us in the audience to experience greater realism and excitement.
